I just remember the math fans did using among other things statement from Trish that Eva died 20 years ago, and it came out as 8, but what were other sources and how accurate it all might have been is a big question.

In the manga's flashbacks, Dante and Vergil look to be at the age close to 10, 12 at most, hard to tell. Dante Alighieri lost his mother around the age of 10, but I don't know how far the inspiration for this Dante goes.

So many questions, I'd really love if they released a timeline.

ps. lol, only first letter is capital in Eva, you're not on the MGS wiki now. XD
